Application med July 2, 1923. serial No. '$48,965. y

reference being had therein to the accoman in drawln P"Thisignventiongrselates to tractors especially designed for moving trailersor other vehicles that may be conveniently coupled to the tractors, andmy invention aims to utiliae a well jlrnown type of tractor for trailermovingpurposes. ln order to do this l nd it necessary to provide atractor attachment which will increase the wheel base of an ordinarytractor and convert it into a vehicle to which a trailer or otherIvehicle may be easily coupled. ln referring to an ordinary andconventional torno. of tractor l have in .fnind the Fordson tractorwhich consists` it having a few parts that may be 'easily separated topermit oit an interposed art oeing used to increase the wheel base ofthe tractor and adord a substantial support tor a tractor trame, onwhich l may place a cab and part ot the coupling mechanism which li haveheretofore used tor-'connecting a trailer to a tractor other than thattype herein disclosed. The tractor attachment therefore includes anextension memberin terposed between the power plant and transmissioncasing ot the Fordson tractor, a trame that may be supported from thepower plant and transmission casing, a cab onthe trame, a couplingmechanism. on the frame in proximity to the cab, and the usual controdevices tor the clutch, transmission mechanism and steering mechanism oithe hordson tractor..-

Themanner in which llconvert a Fordson tractor for my purposes `will behereinafter described .and then claimed .and reference now be had to thedrawings, wherein- Fie 1 is a side elevation ot the tractor" partlybrokenl away' and lpartly in longitudinal section, and

Fig. 2 is a plan ci the samedevoid of the cab and ,artly lbroken away;g' f The .fordson tractor as extensively used cludesgseparable parts, atore part having, am l r other things, a crank case 1, a cylinder bock2, a `iront end bearing 3, a Jfront axle l.tpfront wheels 5, aradiator,a water tank and a fuel tank 8, these various elements contributing tothe power plant of the tractor. The crankcase 1 and the cylinder block2have anges 9 and 10 andthe latter are ordinarily bolted to the iianges11 of the aft part of the tractor, which includes a transmission casing12, a rear axle assembly 13, rear driven wheels 14, anda transmissionvmechanism 15 within the casin 12. The transmission mechanism includes sittable gears actuated by ya changespeed lever f 16 and on the' casing12 is usually mounted adash assembly 17 including a steering column18,'.and a housing 19 tor the upper end of a clutch lever 20. The dashassembly is removed from the transmission 4casing 12 and' the usualopening in the transmission casing 12 may be closed by a plate 21.

' lin order that I may increase the wheel base of the tractor andutilize it ior my purposes, l disconnect the anges 11 and 12 andseparate the fore and aft parts sumciently to permit ot an interposedpart or hollow extension casing 22 being placed between the idanges 10and 11 and bolted or otherwise connected thereto, so that vtheinterposed part 22 will maintain' a rigid tractor bod Since thetransmission mechanism 15 has een separated trom the power plant of thetractor, Il install an extension drive shaft 23 by which power may betransmitted from the lforward end of the tractor to the rear endthereonA rllhe dash assembly which has been removed rfrom thetransmission casing 12de nowmounted on the-interposed part or casing 22,as clearly shown in Fig; 1,

and lf make certain changes inthe control devices for the tractor, aswill hereinafter appear.. f l

ln a horizontal plane above `the'tractor body is an oblong rectangular'trame or chassis 24: which has its forward end attached tothe idanges 9or the forward end .of the power plant by suitable brackets or supports'25, and the rear end oi the `trame, at the sides of the frame, issupported by bracketsy 26 trom the lrear axle assembly. The dashassembly having beentransiterred to the interposed part or extensioncasing 22 supports the rear end oi the iuel .tank 8 in the usual mannerand on the trame 2d, at the dash assembly, ll mount a cab 27 in which isplaced a steering column entension28 convenient to an `operators seat29. ln order that the levers 16 Aand 20 may be actuated iroin within thecab 27, l provide a cab door 30 with a pivoted clutch pedal 31 con titllitt

lll@

nected by a link 32 to a clutch crank33 adapted to actuate the lever 20.Extending through the cab floor 30 is a gear shift lever 34 whlchextends downwardly to the extension casing 22 and is pivotally attachedto a bearing 35 on a longitudinal' rock shaft 36 supported byl bearings37 and 38 of the casings 22 and 12 respectively.1^ By laterally swingingthe ear shift lever 34 the shaft 36 may be roc ed and said shaft,adjacent the bearing 38, has a fork 39 engaging the lever 16 to rocksaid lever in the usual manner preparatory to shifting certain gears.The gear shift lever 34 can also be moved independent of any rockingmovement of the shaft 36 and said gear shift lever is connected by a rod40 to the lever 16, so that after said lever has been adjusted throu hthe medium of the rock shaft 36 it may e further adjusted tolongitudinally shift certain gears and provide for certain speed orreverse in connection with the transmission mechanism.

As set forth in the beginning I have changed the Fordson tractor so thatit may be utilizedv for moving trailers or other vehicles coupled to therear end of the frame 24, especially a trailer or vehicle body of thatty e disclosed in my ending applicationsv ed Nov. 24, 1922, ISer. No.602,928 and Jan. 8, 1923, Ser. No. 611,319. These trailers or bodies areadapted to have the forward ends thereof supported b and coupled toatractor, which may be acked under the forward end of the trailer orbody. Therefore, I provide the rear end of the frame 24 with a platformor turntable 41, an inclined track 42, a draft rig 'ng 43, and acoupling device 44, said coupling device havin control rods or elements/46 that may exten to the cab 27 so as to be operated from therein. Forthe sake of clearness in illustratin my invention, the control elementswit in the cab for controlling the coupling device, trailer brakes,etc., has not been shown, but such elements will be found in my pendingapplication. 1

e cab 27 is somewhat along the lines of the cab shown in my pendingapplication, Ser. No. 602,928 above referred to, the cab having a pocketor undercut portion 45 providing clearance for the forwardfend of thetrailer or low body vehicle, so'that there will be a comparativelyshort.coupling between the tractor and trailer combination.

In yconverting a Fordsontractor to the purposes of -my invention I donot destroy its usefulness or moving vehicles or implements, other thanmy trailers, as access can t at all times be had to the rear axleassembly for the attachment of vehicles or implements thereto. y
